Bonding of two elastomeric materials by means of isocyanate vapors

摘要

The bond strength between an elastomeric material and a secondary material is improved by applying a coating of isocyanate onto the surface of the elastomeric material prior to bonding the secondary material to the surface of the elastomeric material. The isocyanate is applied to the surface of the elastomeric material by exposing the elastomeric material to an atmosphere containing isocyanate vapor which is substantially uniformly distributed throughout the atmosphere and causing the isocyanate to deposit onto the surface of the elastomeric material. Then casting a second material onto the isocyanate coated surface.
